Transfer Panels & Switches


Transfer switches manufactured by Hayley Industrial Electronics Ltd. are an integral element of our UPS Systems. Either mounted into our inverters cabinet or in a separate cabinet, our transfer switches work seamlessly with our inverters in order to supply you with uninterruptable AC power to critical loads.

Transfer switches are available for all applications and sizes. They can be supplied as low speed switches where complete isolation from the incoming power is required or as high speed switches were static elements transfer from inverter to bypass without any break or interruption of power to the load.

Hayley Electronics transfer switches are available for 120Vac at 60 Hz or 220Vac at 50 Hz, both single phase output.


Industrial, office, instrumentation and critical loads are environments ideally suited for Hayley UPS systems.
